To all whom may concern.:-

Be it known that I, GEORGE K. BAINBRID'GE, a citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco, Stateof California, have invented a new and useful Cutting and RollingMachine for Plastic Materials, of which the following is a specificationin such full and clear terms as will enable those skilled in the art toconstruct and use the same.

4This invention relates to a machine vfor cutting and rolling plastlcmaterlals such as'cream candies which must be surfacedplete machine,Fig. 2 is a plan view of the complete machine, Fig. 3 is a sectionalview of the cutter and that portion of the machine which rolls thecut-off lumps of material, Fig. 4 is a vertical sectional view on theline 4-4, Fig. 2, Fig. 5 is a sectional view 'illustrating thesupporting shaft upon which the u per belt frame slides, Fig. 6 is asectiona view illustrating the mounting of one of the rollers in theframes carrying the same, and Fig. 7 is a vertical sectional viewillustrating another of the rollers carrying the rolling belt.

The numeral 1 represents a suitable base vupon which the machine ismounted. This base has a pair of inverted Urshaped frames 2 and 3, whichframes support longitudinally extending bars 4.and which bars form thesupport for two roller shafts 6 and 7.v The bars 4 and 5 are braced-bymeans of two bars 8 and 9 which are bolted to the frames 2 and 3respectively. Connecting the bars 4 and 5 are crosspieces 10, 11,

and 12 which form a support forthe door 13 .upon which the endless belt14 travels.

The endless belt 14 passes' around rollers 15, 16 and over a 'small roll17, which latter prevents the belt from saggin The shaft 6 is carried inioxes 20, 21

which are adjusted by means of the threaded bolts 22, 23, suitable nuts24,25 being used to draw the roll up andhold the belt tight. The shaft 7has a pulley 26 thereon for drivlng 1t, said pulley' receiving powerfrom a belt 27 which passes around a multiple pulley 28 on a short shaft29 supported by the brace 8.

At the upper part ofthe frame there is secured a flat top member 30 forthe support of the operating parts of the upper belt. This member 30 isadjustably supported by means of bolts 31, 32, 33 and 34 which boltshave nuts thereon in Contact with the upper member of the U framessupporting the belt. On the sides the frames 2 and 3 support ahorizontal bar 36 which bar supports a bracket 37 through which a shaft38 extends, said shaft supporting two rollers 39, 40 over which a belt41 extends from the multiple pulley 28 to a pulley 42 on the upper endof the crank shaft 43. The crank shaft is journaled in a box 44 suitablysecured tothe top lmember 30 and its lower end is connected to a shallowU shaped frame 45 in such manner as to permit it to rotate in said frame45 and thus give a gyratory motion to the upper belt.

The upper belt is supported from -the member 30 by means of fourdepending arms 46,47, 48 and 49. Said arms carry two hori' zontal shafts50,v 51, on which shaft-s two longitudinally extending bars 52, 53 are Yslidablc, said bars having outturned lugs at the ends as indicated at54, 55 through which said shafts 50, 51 respectively pass. The bars 52,53 are rigidly connected by two cross shafts 60, 61. The frame whichsupportsv the upper belt comprises two longitudinally extending bars 62,63 rigidly connected together by means of the bolts 64, 65. This framecarries rollers 66, 67 at its ends, the latter beingadjustable, and thebars 62, 63 are slidable on the bars 60, 61, which latter bars areconnected with the supports 52, 53 slidable on the longitudinallyextending rods 50, 51, so that the components of ai lateral andlongitudinal slide of the belt frame imparted by the shaft 43 and frame45 will be a circular or gyratory movement.

The roll 67 is supported upon a shaft 68 which shaft is journaled insuitable bearings 6 9, 7 0,which bearings are rigidly connected to thethreaded. bolts- 71, 72 andv which bolts are acted upon by the nuts 73,74y forshifting the roll 67 and tightening the belt 76 carriedthereby. IThe roll 66 has a worm wheel 77 on its shaft at one end, whichworm wheel is operated by the worm 78 on a flexible shaft 79, the lattershaft having as a bearing a bracket `8O. and having its other endconnected by means of a coupling 81 to the .top of the crank shaft 43.

The Hat member 3() carries a receptacle 8 for the comminuted materialused for surfacing the lumps of material to be treated bythe machine.This receptacle has a shaft 84 extendin-Or thereinto which shaft issupported by the bearing block'85 and driven from the pulley 86 by meansof the belt 87 two brackets 92, 93 which support a base 94 rack pistonrod 107, said rod through a suitable support at 108 andbeing for thepress cylinder 95. .It is to be observedthat the particular type ofpress is immaterial to the invention, the only requisite being that thepress and surfacing machine be driven. in' such harmony as to cut offthe right lengths of the plastic-material and adequately surface them asthey pass out from their treatment bythe two belts. ln the presentinstance the base 94 is extended over the top of the lower belt asindicated atV 96, at which point it has a pair ,of bearings 98, 99zfor ashaft 100, which.

shaft carries arms 101, 102 for the'support of the cutting wire 103. Thecylinder has a spout 104 which extends into proximity of the path, ofthe cutting wire 103 so that as fast as the material is forced out ofthe press it be cut off into small lumps by the wire 103.

The press has a piston 106 operated bythe passing driven by a gear 109on a shaft 110. l.The shaft 110 has a' squared portion 111 to enable thepiston to be withdrawn by manually sliding the driving gear 1121 onf-hefeather 112' out of engagement with the plston.`

small pinion 113, a small hand crank being applied to the shaft 110 foron the base 1-which motor has a belt -114in mesh with the'pulleyll, asmaller pulley A" thereon, over which a chain 121 passes to asprocketgear 122 onthe shaft 100, said retracting the Y shaft alsocarrying apulley 123 around which the cross'belt 124 extends, said beltextending to the multiple pulley 28 for ydriving the machine. v

The operation of the machine is as follows: The cylinder 95 havingbeenfilled with the plastic material to be treated, the piston 106 is placedtherein and turned up by means of a suitable hand crank, not shown,-until the piston engages the plastic material, whereupon the motor maybe started and as it runs the. piston will be pushed forward, while atthe same timev the belts will be caused to travel forward, the upperbelt having a gyratory `motion imparted thereto by the crank 43. At thesame time the arms 101, 102 will be rotated so that small lumps of thematerial .pushed out of the press will drop upon the belt 14 and as ittravels forward they will be rolled in l the surfacing material that isdropped upon they upper belt from the receptacle 83,A so

that when they leave the machine they are properly rounded to be givensuch other treatment as may become necessary. At the same time that thebelt 76 is given the gyratory'motion it is also given a slowlongitudinal motion by means of the flexible shaft 79 and it receivesthe comminuted material for the treatment ofthe lumps, therebycontinually offering a freshly dusted sur/-l face to the lumps to betreated, the lower belt moving them through the machine. The surplusmateria-l1 falling olf the upper belt is sufficient to dust thelowerbelt mak- 'ing an additional duster unnecessary ordinarily. I Y

`Having thus described my invention what I claim as new and desire tosecure by' Letters Patent of the United States, is as folj lows,modiiic'ations within the scope of the claims bein expressly reserved:
